wkcn commented on issue #15624: asnumpy() took a lot of time when converting NDARRAY into numpy? URL: https://github.com/apache/incubator-mxnet/issues/15624#issuecomment-513868734 Yes, it is correct. When using GPU context, MXNet need to allocate GPU memory in the first time. After that, MXNet can get the memory allocation from the memory pool, so it takes less time. It takes more time to allocate GPU memory than allocating CPU memory.
